led - How to ignore pulse in a circuit



I have a 12v cable that sometimes pass (75%on-25%off) and other times 100%on.


What can I put on that cable so if the input is (75%on-25%off) then the output is 0v, and if the input is 100%on the output is 12v?


Is a resistor what I need?

Here i want the purple LED only to be on when the brake light is 100%. Right now if is 75% the purple LED is flickering.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
